Product Description

Methyl Tetra-Hydro Phthalic Anhydride

Description

MTHPA is primarily utilized as a curing agent for epoxy resins. It blends readily with various liquid resins to form stable, low viscosity mixtures. It is extensively applied in casting, potting, impregnation, and lamination processes. In reinforced plastics

manufacturing, it is ideal for filament winding applications such as oil pipes, utility poles, and sporting goods, as well as

laminated sheets and switchgear components. Leveraging its superior electrical insulation characteristics, MTHPA is widely

employed in the production of electrical components including capacitors, resistors, and ignition coils.
